Today I will show you how to make a easy IronMan arc reactor necklace out of a DVD drive motor and a blue LED.

Step 1: Tools and Parts

The tools and parts you need are:

DVD motor
Long piece of wire
To small Neodymium magnets
Wire stripers
Pliers
Hot Glue gun
Drill
Grinder

Step 2: Removing Your Rotor With Windings

First you pry the off the stator (or case) of the motor. I used a flathead screwdriver to pry it off. Now grind the bottom of the center piece and drill or tap out the center piece from the rotor.

Step 3: LED and Hot Glue

Now grind the LED down to about 1mm from the metal inside the LED and Hot Glue the LED in the rotor. Sand down the dome of Hot Glue to make it look more realistic.

Step 4: Power and Wire

Cut and strip the wires and connect it to the LED and Hot Glue the wires in place. Twist the wire on the magnet and Hot Glue it in place then mark the polarities on the magnet. Connect the button cell batteries between the magnets and it will light up. If it dose not light up check the polarities and the LED connections.
